FIELD OF THE INVENTION

This invention relates to methods of treating cancer with a compoundthat modulates the Hedgehog pathway and the resultant modulation ofcellular activities (such as proliferation, differentiation, programmedcell death, migration, chemoinvasion and metabolism) alone or incombination with anticancer agents.

BACKGROUND OF THE INVENTION

Hedgehog (Hh) proteins are understood as a family of secreted signalproteins which are responsible for the formation of numerous structuresin embryogenesis (J. C. Smith, Cell 76 (1994) 193 196, N. Perrimon, Cell80 (1995) 517 520, C. Chiang et al., Nature 83 (1996) 407, M. J. Bitgoodet al., Curr. Biol. 6 (1996) 296, A. Vortkamp et al., Science 273 (1996)613, C. J. Lai et al., Development 121 (1995) 2349). During itsbiosynthesis a 20 kD N-terminal domain and a 25 kD C-terminal domain areobtained after cleavage of the signal sequence and autocatalyticcleavage. In the naturally occurring protein the N-terminal domain ismodified with cholesterol at its C-terminus after cleavage of theC-terminal domain (J. A. Porter et al., Science 274 (1996) 255 259). Inhigher life-forms the Hh family is composed of at least three membersnamely sonic, indian and desert Hh (sHh, IHh, DHh; M. Fletz et al.,Development (Suppl.) (1994) 43 51). Differences in the activity ofhedgehog proteins that were produced recombinantly were observed afterproduction in prokaryotes and eukaryotes (M. Hynes et al., Neuron 15(1995) 35 44 and T. Nakamura et al., Biochem. Biophys. Res. Comm. 237(1997) 485 469).

Improvements in the specificity of agents used to treat various diseasestates such as cancer, metabolic, and inflammatory diseases is ofconsiderable interest because of the therapeutic benefits which would berealized if the side effects associated with the administration of theseagents could be reduced. Traditionally, dramatic improvements in thetreatment of cancer are associated with identification of therapeuticagents acting through novel mechanisms.

Aberrant hedgehog (Hh) pathway signaling has been implicated in humanmalignancies ranging from semi-malignant tumors of the skin to highlyaggressive cancers of the brain, lung, pancreas, breast, prostate andlymphoid lineages (Rubin, L. L. and de Sauvage, F. J. Nat Rev DrugDiscov, 2006, 5, 1026-1033). Dysregulation of this pathway contributesto uncontrolled proliferation, invasion, metastasis, evasion ofapoptosis and resistance to chemotherapy treatments through regulationof the GLI family of transcription factors (GLI1-3), which reside at thedistal end of the pathway (Kasper, M., et. al. Eur J Cancer, 2006, 42,437-445). The initial evidence that aberrant Hh signaling plays acritical role in cancer initiation and/or progression came from theobservations that important regulatory pathway components are mutated ina number of cancers. These include loss-of-function mutations in the12-transmembrane Hh receptor, patched1 (PTCH1) and activating mutationsin the 7-transmembrane “GPCR-like” protein smoothened (SMO) observed inbasal cell carcinomas, medulloblastomas and rhabdomyosaracomas. (SeeJohnson et. al. Science, 272: 1668-1671, 1996; Hahn, et. al. Cell, 85:841-851, 1996; Unden, et. al. Cancer Res, 56: 4562-4565, 1996; andChidambaram, et. al. Cancer Res, 56: 4599-4601, 1996).

Where a Sporadic loss-of-function mutation in PTCH1 is observed, thesecancers are implicated: basal cell carcinomas (Wolter, M., et. al.Cancer Res, 1997, 57, 2581-2585; Reifenberger, J., et. al. Cancer Res,1998, 58, 1798-1803; Lam, C. W., et. al. Oncogene, 1999, 18, 833-836;Couve-Privat, S., et. al. Cancer Res, 2002, 62, 7186-7189; Xie, J., et.al. Nature, 1998, 391, 90-92), medulloblastomas (Wolter, M., et. al.Cancer Res, 1997, 57, 2581-2585; Raffel, C., et. al. Cancer Res, 1997,57, 842-845; Pietsch, T., et. al. Cancer Res, 1997, 57, 2085-2088;Vorechovsky, I., et. al. Oncogene, 1997, 15, 361-366; Couve-Privat, S.,et. al. Cancer Res, 2002, 62, 7186-7189; Xie, J., et. al. Nature, 1998,391, 90-92), breast carcinomas (Xie, J., et. al. Cancer Res, 1997, 57,2369-2372), meningiomas (id.), and rhabdomyosarcoma (Calzada-Wack, J.,et. al. Hum Mutat, 2002, 20, 233-234).

In addition, the activity of the Hh pathway has been shown to becritical for the growth and metastasis of a number of tumors that do notcontain mutations within any of the defined pathway components includingthose of the pancreas (Bennan, D. et. al. Nature, 425: 846-851, 2003;Thayer, S. P., et. al. Nature 2003, 425, 851-856; Pasca di Magliano, M.,Genes Dev, 20: 3161-3173, 2006; and Gao, J., et. al. Gene Ther, 13:1587-1594, 2006), prostate (Karhadkar, S. S., et. al. Nature, 431:707-712, 2004; Sanchez, P., et. al. Proc Natl Acad Sci USA, 101:12561-12566, 2004; Sheng, T., et. al. Mol Cancer, 3: 29, 2004; and Fan,L., et. al. Endocrinology, 145: 3961-3970, 2004), digestive tract(Berman, D. et. al. Nature, 425: 846-851, 2003; Thayer, S. P., et. al.Nature 2003, 425, 851-856; Fukaya, M., et. al. Gastroenterology, 131:14-29, 2006; Ohta, M., et. al. Cancer Res, 65: 10822-10829, 2005), andsmall cell lung cancers (Watkins, D. N., et. al. Nature, 422: 313-317,2003), and non-small cell lung cancers (Yuan, Z., et. al. Oncogene, 26:1046-1055, 2007).

The Hh pathway components are implicated in esophageal cancer (Ma, X.,et. al. Int J Cancer, 118: 139-148, 2006; Berman, D. et. al. Nature,425: 846-851, 2003) and are highly expressed in the vast majority (87%,n=43) of chemotherapy-resistant esophageal cancer specimens(Sims-Mourtada, J. et. al. Clin Cancer Res, 12: 6565-6572, 2006). Othercancers where the Hh pathway are involved include biliary tract cancers(Berman, D. et. al. Nature, 425: 846-851, 2003), melanoma (Stecca, B.,et. al. Proc Natl Acad Sci USA, 104: 5895-5900, 2007), and stomachcancer (Berman, D. et. al. Nature, 425: 846-851, 2003; Ma, X., et. al.Carcinogenesis, 26: 1698-1705, 2005). Tumors that contain highlyproliferative “tumor stem cells” and which represent areas of therapyinclude glial cell cancers (Clement, V., et. al. Curr Biol, 17: 165-172,2007), prostate cancers (Li, C., Heidt, et. al. Cancer Res, 67:1030-1037, 2007), breast cancers (Liu, S., et. al. Cancer Res, 66:6063-6071, 2006), multiple myelomas (Peacock, C. D., et. al. PNAS, 104:4048-4053, 2007), and colon cancers (Ricci-Vitiani, L., et. al. Nature,445: 111-115, 2007).

Finally, the Hh pathway is an essential regulator of “cancer stem cells(CSC)”, which are discrete tumor cell populations that display highlyenhanced survival, self-renewal, and tumorigenicity properties (Beachy,P. A., et. al. Nature, 432: 324-331, 2004). Activation of the Hh pathwayhas been shown to be critical for CSCs of the breast (Liu, S., et. al.Cancer Res, 66: 6063-6071, 2006), central nervous system (Clement, V.,Curr Biol, 17: 165-172, 2007) as well as in hematological malignancies(Peacock, C. D., PNAS, 104: 4048-4053, 2007). These cells, in someexperimental contexts, have shown to confer resistance to currently usedchemotherapy (Bao, S., et. al. Nature, 444: 756-760, 2006; Dean, M., et.al. Nat Rev Cancer, 5: 275-284, 2005). Therefore, a Hh pathway inhibitormay have broad clinical utility treating of a wide range ofchemotherapy-resistant malignancies.

In view of the important role of the Hedgehog pathway in biologicalprocesses and disease states, modulators of this pathway are desirable.

General Administration

In one aspect, the invention provides pharmaceutical compositionscomprising a modulator of the Hedgehog pathway according to theinvention and a pharmaceutically acceptable carrier, excipient, ordiluent. In certain other embodiments, administration may be by the oralroute. Administration of the compounds of the invention, or theirpharmaceutically acceptable salts, in pure form or in an appropriatepharmaceutical composition, can be carried out via any of the acceptedmodes of administration or agents for serving similar utilities. Thus,administration can be, for example, orally, nasally, parenterally(intravenous, intramuscular, or subcutaneous), topically, transdermally,intravaginally, intravesically, intracistemally, or rectally, in theform of solid, semi-solid, lyophilized powder, or liquid dosage forms,such as for example, tablets, suppositories, pills, soft elastic andhard gelatin capsules, powders, solutions, suspensions, or aerosols, orthe like, in unit dosage forms suitable for simple administration ofprecise dosages. When treating brain cancers, including glioblastomas,the administration may be by placing a gliadel, a dissolvable materialthat contains the chemotherapy drug (in particular BCNU), directly intobrain tumors during an operation.

The compositions will include a compound of Formula I or II as the/anactive agent and can include a conventional pharmaceutical carrier orexcipient and in addition may include other medicinal agents andpharmaceutical agents that are generally administered to a patient beingtreated for cancer.

Adjuvants include preserving, wetting, suspending, sweetening,flavoring, perfuming, emulsifying, and dispensing agents. Prevention ofthe action of microorganisms can be ensured by various antibacterial andantifungal agents, for example, parabens, chlorobutanol, phenol, sorbicacid, and the like. It may also be desirable to include isotonic agents,for example sugars, sodium chloride, and the like. Prolonged absorptionof the injectable pharmaceutical form can be brought about by the use ofagents delaying absorption, for example, aluminum monostearate andgelatin.

If desired, a pharmaceutical composition of the invention may alsocontain minor amounts of auxiliary substances such as wetting oremulsifying agents, pH buffering agents, antioxidants, and the like,such as, for example, citric acid, sorbitan monolaurate, triethanolamineoleate, butylated hydroxytoluene, etc.

The choice of formulation depends on various factors such as the mode ofdrug administration (e.g., for oral administration, formulations in theform of tablets, pills or capsules) and the bioavailability of the drugsubstance. Recently, pharmaceutical formulations have been developedespecially for drugs that show poor bioavailability based upon theprinciple that bioavailability can be increased by increasing thesurface area i.e., decreasing particle size. For example, U.S. Pat. No.4,107,288 describes a pharmaceutical formulation having particles in thesize range from 10 to 1,000 nm in which the active material is supportedon a crosslinked matrix of macromolecules. U.S. Pat. No. 5,145,684describes the production of a pharmaceutical formulation in which thedrug substance is pulverized to nanoparticles (average particle size of400 nm) in the presence of a surface modifier and then dispersed in aliquid medium to give a pharmaceutical formulation that exhibitsremarkably high bioavailability.

Compositions suitable for parenteral injection may comprisephysiologically acceptable sterile aqueous or nonaqueous solutions,dispersions, suspensions or emulsions, and sterile powders forreconstitution into sterile injectable solutions or dispersions.Examples of suitable aqueous and nonaqueous carriers, diluents, solventsor vehicles include water, ethanol, polyols (propyleneglycol,polyethyleneglycol, glycerol, and the like), suitable mixtures thereof,vegetable oils (such as olive oil) and injectable organic esters such asethyl oleate. Proper fluidity can be maintained, for example, by the useof a coating such as lecithin, by the maintenance of the requiredparticle size in the case of dispersions and by the use of surfactants.

One route of administration is oral, using a convenient daily dosageregimen that can be adjusted according to the degree of severity of thedisease-state to be treated.

Solid dosage forms for oral administration include capsules, tablets,pills, powders, and granules. In such solid dosage forms, the activecompound is admixed with at least one inert customary excipient (orcarrier) such as sodium citrate or dicalcium phosphate or (a) fillers orextenders, as for example, starches, lactose, sucrose, glucose,mannitol, and silicic acid, (b) binders, as for example, cellulosederivatives, starch, alignates, gelatin, polyvinylpyrrolidone, sucrose,and gum acacia, (c) humectants, as for example, glycerol, (d)disintegrating agents, as for example, agar-agar, calcium carbonate,potato or tapioca starch, alginic acid, croscarmellose sodium, complexsilicates, and sodium carbonate, (e) solution retarders, as for exampleparaffin, (f) absorption accelerators, as for example, quaternaryammonium compounds, (g) wetting agents, as for example, cetyl alcohol,and glycerol monostearate, magnesium stearate and the like (h)adsorbents, as for example, kaolin and bentonite, and (i) lubricants, asfor example, talc, calcium stearate, magnesium stearate, solidpolyethylene glycols, sodium lauryl sulfate, or mixtures thereof. In thecase of capsules, tablets, and pills, the dosage forms may also comprisebuffering agents.

Solid dosage forms as described above can be prepared with coatings andshells, such as enteric coatings and others well known in the art. Theymay contain pacifying agents, and can also be of such composition thatthey release the active compound or compounds in a certain part of theintestinal tract in a delayed manner. Examples of embedded compositionsthat can be used are polymeric substances and waxes. The activecompounds can also be in microencapsulated form, if appropriate, withone or more of the above-mentioned excipients.

Liquid dosage forms for oral administration include pharmaceuticallyacceptable emulsions, solutions, suspensions, syrups, and elixirs. Suchdosage forms are prepared, for example, by dissolving, dispersing, etc.,a compound(s) of the invention, or a pharmaceutically acceptable salt,hydrate, solvate or combination thereof, and optional pharmaceuticaladjuvants in a carrier, such as, for example, water, saline, aqueousdextrose, glycerol, ethanol and the like; solubilizing agents andemulsifiers, as for example, ethyl alcohol, isopropyl alcohol, ethylcarbonate, ethyl acetate, benzyl alcohol, benzyl benzoate,propyleneglycol, 1,3-butyleneglycol, dimethylformamide; oils, inparticular, cottonseed oil, groundnut oil, corn germ oil, olive oil,castor oil and sesame oil, glycerol, tetrahydrofurfuryl alcohol,polyethyleneglycols and fatty acid esters of sorbitan; or mixtures ofthese substances, and the like, to thereby form a solution orsuspension.

Suspensions, in addition to the active compounds, may contain suspendingagents, as for example, ethoxylated isostearyl alcohols, polyoxyethylenesorbitol and sorbitan esters, microcrystalline cellulose, aluminummetahydroxide, bentonite, agar-agar and tragacanth, or mixtures of thesesubstances, and the like.

Compositions for rectal administrations are, for example, suppositoriesthat can be prepared by mixing the compounds of the present inventionwith for example suitable non-irritating excipients or carriers such ascocoa butter, polyethyleneglycol or a suppository wax, which are solidat ordinary temperatures but liquid at body temperature and therefore,melt while in a suitable body cavity and release the active componenttherein.

Dosage forms for topical administration of a compound of this inventioninclude ointments, powders, sprays, and inhalants. The active componentis admixed under sterile conditions with a physiologically acceptablecarrier and any preservatives, buffers, or propellants as may berequired. Ophthalmic formulations, eye ointments, powders, and solutionsare also contemplated as being within the scope of this invention.

Compressed gases may be used to disperse a compound of this invention inaerosol form. Inert gases suitable for this purpose are nitrogen, carbondioxide, etc.

Generally, depending on the intended mode of administration, thepharmaceutically acceptable compositions will contain about 1% to about99% by weight of a compound(s) of the invention, or a pharmaceuticallyacceptable salt, hydrate, solvate or combination thereof, and 99% to 1%by weight of a suitable pharmaceutical excipient. In one example, thecomposition will be between about 5% and about 75% by weight of acompound(s) of the invention, or a pharmaceutically acceptable salt,hydrate, solvate or combination thereof, with the rest being suitablepharmaceutical excipients.

Actual methods of preparing such dosage forms are known, or will beapparent, to those skilled in this art; for example, see Remington'sPharmaceutical Sciences, 18th Ed., (Mack Publishing Company, Easton,Pa., 1990). The composition to be administered will, in any event,contain a therapeutically effective amount of a compound of theinvention, or a pharmaceutically acceptable salt, hydrate, solvate orcombination thereof, for treatment of a disease-state in accordance withthe teachings of this invention.

The compounds of the invention, or their pharmaceutically acceptablesalts, hydrates, solvates or combinations thereof, are administered in atherapeutically effective amount which will vary depending upon avariety of factors including the activity of the specific compoundemployed, the metabolic stability and length of action of the compound,the age, body weight, general health, sex, diet, mode and time ofadministration, rate of excretion, drug combination, the severity of theparticular disease-states, and the host undergoing therapy. Thecompounds of the present invention can be administered to a patient atdosage levels in the range of about 0.1 to about 1,000 mg per day. For anormal human adult having a body weight of about 70 kilograms, a dosagein the range of about 0.01 to about 300 mg per kilogram of body weightper day is an example. In another example the dose range is 3-100 mg/kgof body weight per day. The specific dosage used, however, can vary. Forexample, the dosage can depend on a number of factors including therequirements of the patient, the severity of the condition beingtreated, and the pharmacological activity of the compound being used.The determination of optimum dosages for a particular patient is wellknown to one of ordinary skill in the art.

If formulated as a fixed dose, such combination products employ thecompounds of this invention within the dosage range described above andthe other pharmaceutically active agent(s) within its approved dosagerange. Compounds of the instant invention may alternatively be usedsequentially with known pharmaceutically acceptable agent(s) when acombination formulation is inappropriate.

Certain compounds of Formula I have been tested using the assaydescribed in Biological Examples 1 and 2 and have been determined to bemodulators of the Hedgehog pathway. As such compounds of Formula I areuseful for treating diseases, particularly cancer in which Hedgehogpathway activity contributes to the pathology and/or symptomatology ofthe disease. For example, cancer in which Hedgehog pathway activitycontributes to its pathology and/or symptomatology include basal cellcarcinomas, medulloblastomas, rhabdomyosaracomas, breast carcinomas,meningiomas, pancreatic cancers, stomach cancers, esophageal cancers,biliary tract cancers, prostate cancers, small cell lung cancers,non-small cell lung cancers, glial cell cancers, multiple myelomas, andcolon cancers, and the like.

Suitable in vitro assays for measuring Hedgehog pathway activity and theinhibition thereof by compounds are known. For example, see Chen et al.,Proc Natl Acad Sci USA 2002, 99, 14071-14076. Also see Chen et. al.Genes Dev 2002, 16, 2743-2748. For further details of in vitro assaysfor measuring cellular activity, see Biological Examples 1, 2, 3, 4, and5, infra. Suitable in vivo models of cancer are known to those ofordinary skill in the art. For further details of in vivo assays seeBiological Examples 6-9, infra. A pharmacodynamic assay is described inBiological Example 10. Efficacy models are described in Examples 11-12.Following the examples disclosed herein, as well as that disclosed inthe art, a person of ordinary skill in the art can determine the abilityof a compound of this invention to modulate Hedgehog pathway activity.

Preparations of the Intermediates and Compounds of the Invention

Prodrugs can be prepared by techniques known to one skilled in the art.These techniques generally modify appropriate functional groups in agiven compound. These modified functional groups regenerate originalfunctional groups by routine manipulation or in vivo. Amides and estersof the compounds of the present invention may be prepared according toconventional methods. A thorough discussion of prodrugs is provided inT. Higuchi and V. Stella, “Pro-drugs as Novel Delivery Systems,” Vol 14of the A.C.S. Symposium Series, and in Bioreversible Carriers in DrugDesign, ed. Edward B. Roche, American Pharmaceutical Association andPergamon Press, 1987, both of which are incorporated herein by referencefor all purposes.

The compounds of the invention, or their pharmaceutically acceptablesalts, hydrates, solvates or combinations thereof, may have asymmetriccarbon atoms or quaternized nitrogen atoms in their structure. Compoundsof Formula I that may be prepared through the syntheses described hereinmay exist as single stereoisomers, racemates, and as mixtures ofenantiomers and diastereomers. The compounds may also exist as geometricisomers. All such single stereoisomers, racemates and mixtures thereof,and geometric isomers are intended to be within the scope of thisinvention. When the term “single isomer” is used, it includes the termsstereoisomer, enantiomer, diastereomer, geometric isomer, and atropeisomer.

Some of the compounds of the invention may exist as tautomers. Forexample, where a ketone or aldehyde is present, the molecule may existin the enol form; where an amide is present, the molecule may exist asthe imidic acid; and where an enamine is present, the molecule may existas an imine. All such tautomers are within the scope of the invention.

The present invention also includes N-oxide derivatives and protectedderivatives of compounds of Formula I. For example, when compounds ofFormula I contain an oxidizable nitrogen atom, the nitrogen atom can beconverted to an N-oxide by methods well known in the art. When compoundsof Formula I contain groups such as hydroxy, carboxy, thiol or any groupcontaining a nitrogen atom(s), these groups can be protected with asuitable “protecting group” or “protective group”. A comprehensive listof suitable protective groups can be found in T. W. Greene, ProtectiveGroups in Organic Synthesis, John Wiley & Sons, Inc. 1991, thedisclosure of which is incorporated herein by reference in its entirety.The protected derivatives of compounds of Formula I can be prepared bymethods well known in the art.

Methods for the preparation and/or separation and isolation of singlestereoisomers from racemic mixtures or non-racemic mixtures ofstereoisomers are well known in the art. For example, optically active(R)- and (S)-isomers may be prepared using chiral synthons or chiralreagents, or resolved using conventional techniques. Enantiomers (R- andS-isomers) may be resolved by methods known to one of ordinary skill inthe art, for example by: formation of diastereoisomeric salts orcomplexes which may be separated, for example, by crystallization; viaformation of diastereoisomeric derivatives which may be separated, forexample, by crystallization, selective reaction of one enantiomer withan enantiomer-specific reagent, for example enzymatic oxidation orreduction, followed by separation of the modified and unmodifiedenantiomers; or gas-liquid or liquid chromatography in a chiralenvironment, for example on a chiral support, such as silica with abound chiral ligand or in the presence of a chiral solvent. It will beappreciated that where a desired enantiomer is converted into anotherchemical entity by one of the separation procedures described above, afurther step may be required to liberate the desired enantiomeric form.Alternatively, specific enantiomer may be synthesized by asymmetricsynthesis using optically active reagents, substrates, catalysts orsolvents or by converting on enantiomer to the other by asymmetrictransformation. For a mixture of enantiomers, enriched in a particularenantiomer, the major component enantiomer may be further enriched (withconcomitant loss in yield) by recrystallization.

In addition, the compounds of the present invention can exist inunsolvated as well as solvated forms with pharmaceutically acceptablesolvents such as water, ethanol, and the like. In general, the solvatedforms are considered equivalent to the unsolvated forms for the purposesof the present invention.

EXAMPLE 190N-{5-[(dimethylamino)methyl]-2-methylphenyl}-4-[(4-pyridin-2-ylquinazolin-2-yl)amino]benzamide

A solution of 2-aminophenyl-2-pyridyl ketone (0.95 g, 4.8 mmol), urea(500 mg, 8.3 mmol) and acetic acid (10 mL) was stirred at 110° C. for 18h. The reaction mixture was cooled to rt and filtered. The solid waswashed with water and dried under reduced pressure to give4-(pyridin-2-yl)quinazolin-2(1H)-one as a yellow solid (0.83 g, 78%),which was dissolved in phosphorous oxychloride (3 mL) and the mixturewas stirred at reflux for 30 min. The reaction mixture was cooled to rtand slowly poured over an ice/water mixture. The mixture was filteredand the solid was dried under reduced pressure to give2-chloro-4-(pyridin-2-yl)quinazoline as an off-white solid (56 mg, 6%).

To a solution of 2-chloro-4-(pyridin-2-yl)quinazoline (60 mg, 0.25 mmol)in butanol was added 4-aminobenzoic acid (36 mg, 0.26 mmol) and thestirred mixture was heated to reflux for 20 min, after which time thereaction mixture was cooled and the solvent removed on a rotaryevaporator. The residue was redissolved in dimethylformamide (20 mL) and5-((dimethyl-amino)methyl)-2-methylaniline (50 mg, 0.30 mmol), HATU (170mg, 0.45 mmol) and Hunig's base (150 μL, 0.87 mmol) were added to thesolution. The stirred mixture was heated to 70° C. for 18 h, thendiluted with ethyl acetate and the solution was extracted with 10%aqueous lithium chloride and 1 N hydrochloric acid.

To a suspension of magnesium (1.8 g, 74 mmol) in dry THF (50 mL) in aflame-dried round bottomed flask under nitrogen was added4-chloro-1-methylpiperidine (9.0 g, 68 mmol). A crystal of iodine and acatalytic amount of cyclohexylmagnesium chloride was added and themixture was heated to reflux for 2 h. A gray precipitate formed, whichwas removed via vacuum filtration under a nitrogen atmosphere. To thefiltrate was added a solution of 2-aminobenzonitrile (1.6 g, 14 mmol) indry THF (15 mL). The stirred mixture was heated to 45° C. for 2 h. Icewas added and the reaction was quenched with 1 M sulfuric acid. Themixture was extracted with ethyl acetate and the acidic aqueous layerwas then neutralized with 1 N sodium hydroxide, concentrated on a rotaryevaporator and extracted with ethyl acetate. The combined organics weredried over sodium sulfate, filtered and concentrated to afford(2-aminophenyl)(1-methylpiperidin-4-yl)methanone as a yellow oil (1.0 g,7%).

A stirred mixture of (2-aminophenyl)(1-methylpiperidin-4-yl)methanone(1.10 g, 4.58 mmol), urea (550 mg, 9.17 mmol) and acetic acid (15 mL)was heated to overnight. The mixture was cooled to rt, neutralized with1 N sodium hydroxide and concentrated to ˜10 mL on a rotary evaporator.The aqueous residue was extracted with ethyl acetate and the combinedorganics were dried over sodium sulfate, filtered and concentrated on arotary evaporator to afford4-(1-methylpiperidin-4-yl)quinazolin-2(1H)-one as a yellow solid (1.10g, 97%).

A stirred mixture of 4-(1-methylpiperidin-4-yl)quinazolin-2(1H)-one (500mg, 2.29 mmol) and phosphorous oxychloride (5 mL, 56 mmol) was heated toreflux for 3 h. The reaction was then concentrated on a rotaryevaporator and treated with ice water. The aqueous mixture was thenextracted with ethyl acetate, and the combined organic extracts weredried over sodium sulfate, filtered and concentrated on a rotaryevaporator. The residue was treated with 4-aminobenzoic acid (534 mg,3.90 mmol), triethylamine (660 μL, 4.58 mmol) and n-butanol (5 mL) andthe mixture was heated to 140° C. for 25 min. The mixture was cooled andthe solvent removed on a rotary evaporator. This material was thentreated with HATU (1.63 g, 4.29 mmol) and Hunig's base (1.1 mL, 6.3mmol) in dimethylformamide (10 mL) and the mixture stirred until itbecame homogenous. To this mixture was added 2,6-dimethylaniline (620mg, 5.12 mmol) and the reaction was heated to 50° C. overnight. Themixture was cooled to rt, diluted with water and extracted with ethylacetate. The combined organic extracts were washed with 1 N sodiumbicarbonate and a 5% aqueous solution of lithium chloride, then wasextracted with 1 N hydrochloric acid. The combined acidic washes wereneutralized with 1 N sodium hydroxide and extracted withdichloromethane.

BIOLOGICAL EXAMPLES Biological Example 1 Light II Assay

The SHh-Smo assay is a cell-based reporter assay in the SHh Light IIcell line (NIH-3T3), available through the American Tissue CultureCenter (ATCC). This cell line harbors a Gli-luciferase (firefly)reporter which displays 6-14-fold induction upon stimulation with theN-terminal fragment of recombinant hedgehog protein or the smallmolecule agonist HhAg1.5 (Frank-Kamenetsky, et. al. J Bio, 2002, 1,10.). In addition, this cell line contains a constitutively expressedrenilla luciferase reporter (via CMV promoter) which can be used as areadout to detect any non-specific compound effects, includingcytotoxicity.

Test compounds were serially diluted in DMSO and 1.5 μL aliquots weretransferred to 384-well non-binding plates. Compounds were diluted with85 μL of assay media (DMEM+0.5% FBS, 5 mM Hepes, 1% NEAA, 1% PenStrep,0.8% Geneticin). Cell plates were prepared by adding 50 μL of assaymedia (240 cells/μL) to white TC coated 384-well plates (final cellconcentration is 12,000 cells/well). Cell plates were incubatedovernight at 37° C.

Media was removed from the cell plates and 30 μL of compound in assaymedia+rSHh (1.5 μg/well) was added to the cell plates. Plates wereincubated at 37° C. for 24 hours. Following overnight incubation, mediawas aspirated from the cell plates and 20 μL of luciferase media(Bright-glo, Promega) was added to the cell. Cells were incubated for 5minutes and measured on an Envision™ plate reader (Perkn Elmer) usingthe luciferase detection protocol. IC₅₀ values were calculated as apercentage inhibition of luciferase signal from rSHh stimulated cellscompared to unstimulated cells.

Biological Example 2 Daoy-Gli1 Assay

Daoy is a human medulloblastoma line that responds to sonic hedgehog byinduction of numerous genes including the pathway components Gli1 andPTCH1. This assay measures the Hh-specific induction of an endogenoustarget gene in a human tumor cell line. Activating mutations in theGPCR-like receptor Smoothened (Smo) are found in around 40% of sporadicBCC (6, 12-14) and 25% of primitive neuroectodermal tumours (12, 14).Forced expression of the mutant Smo receptors in the Daoymedulloblastoma cell line (W353L and S533N) results in elevated pathwayactivity that is not further induced by the addition of rSHh-N. Theseengineered cell lines, Daoy_Smo_W535L and Daoy_Smo_S533N, were used toassess the ability of compounds to inhibit the function of apathologically relevant mutant receptor.

Daoy cells were plated at 3×10⁴ cells/well in 96-well plates in MEM/10%FCS, and the following day cells were serum-starved in MEM/0.05% FCS for24 hrs. Cells were subsequently treated for 24 hrs with 50 μg/mL rSHh-Nin MEM/0.05% FCS/0.3% DMSO plus or minus compounds. KAAD-cyclopamine wasthe control antagonist. The starting dose was 1000 nM for the Compoundsof the Invention. Compound treatments were done in triplicate assix-point doses with four-fold serial dilutions. Following compoundtreatment, mRNA isolation, cDNA synthesis, and TaqMan® reactions weredone with the following kits: mRNA Catcher™ (Invitrogen) and TaqMan®(Applied Biosystems). TaqMan® reactions were done in quadruplicate usingduplexed probes for Gli1 (target) and β2-macroglobulin (control). Gli1induction by rSHh is generally ten-fold to twenty-fold using thisprotocol.

Biological Example 3 Hedgehog Cell-Based Readout Real Time PCR (Taqman®)Assay in KYSE-180 Cells

KYSE-180 is a human esophageal cancer line shown to be responsive to SHhstimulation as measured by the induction of numerous Hh-responsivegenes, including the pathway Gli1 and PTCH1. This assay measures theHh-specific induction of an endogenous target gene in a human tumor cellline.

KYSE-180 cells were plated at 1.4×10⁵ cells in RPMI/10% FCS in 96-wellplates. The following day cells were serum-starved in MEM/0.05% FCS for24 hrs. Cells were subsequently treated for 24 hrs in MEM/0.05% FCS/0.3%DMSO plus or minus compounds.

TaqMan® reactions weredone in quadruplicate using duplexed probes for Gli1 (target) andβ2-macroglobulin (control). Gli1 induction by rSHh is generallyfive-fold to ten-fold for KYSE-180 cells using this protocol.

Biological Example 4 Hedgehog Cell-Based Readouts Gli1, Gl2 and Gli3Protein Accumulation

Both Gli1 and Gli2 has been shown to function primarily as atranscriptional activator and elevated Hh signaling results in theaccumulation of the active Gli1 and Gli2 proteins. On the other hand,Gli3 has both transcriptional activator and repressor functions. In theabsence of Hh signaling, the larger Gli3 activator (Gli3A, 190 kDa) isprocessed to the smaller repressor form (Gli3R, 85 kDa), whilestimulation of the pathway results in the accumulation of Gli3A at theexpense of the Gli3R. Assessing the levels of these proximal readouts inHh-responsive cell lines in vitro and in vivo (from tumor xenografts)provides a direct readout for pathway activation.

Biological Example 5 Hedgehog Cell-Based Readouts Gli1, Gl2 and Gli3Protein Accumulation Immunoprecipitation (IP)-Western Protocol

Three μg of capture antibody (anti-Gli1 (AF3324, R&D Systems, anti-Gli2(sc-28674, Santa Cruz Biotechnology) or anti-Gli3 (sc-20688, Santa CruzBiotechnology) were independently incubated with 2000 μg of totalprotein from cleared lysates (from tumors or cell-based studies) wereused overnight at 4° C. in the presence of 20 μL of protein G-coatedSepharose beads (Amersham). The beads were washed four times with lysisbuffer (50 mM Tris-HCl, pH 8.0, 150 mM NaCl, 1% Triton X-100, 0.1% SDS,0.5% sodium deoxycholate, 1 mM EDTA, 50 mM NaF, 1 mM sodiumpyrophosphate, 1 mM sodium orthovanadate, 2 mM phenylmethylsulfonylfluoride, 10 μg/ml aprotinin, 5 μg/mL leupeptin and 5 μg/mL pepstatinA).

Biological Examples 6-9 Pharmacodynamic Xenograft Tumor Models

Daoy Human Medulloblastoma Cell Line

The human Daoy medulloblastoma cell line was engineered to over-expressthe N-terminal domain of sonic hedgeghog (SHh-N). A single clone(clone4) of this line with elevated levels of SHh (verified by Taqman®analysis) was chosen based on high levels of in vitro expression of Gli1and Ptch1 mRNA. Furthermore, analysis of this clone grown as a xenograftin female athymic mice revealed elevated levels of both human and mouseHh responsive genes (Gli1 and Ptch1) when compared to tumors comprisedof the parental Daoy cell line as assessed in real-time PCR (Taqman®)assays with species specific primers. Therefore, this cell line wasutilized to assess the ability of hedgehog pathway inhibitors tomodulate the activity of the pathway in vivo.

Intradermal (ID) tumors were generated by implanting 5×10⁶ cells (inHBSS)+50% Matrigel (in HBSS) into the hind flank of nude mice. Compoundswere administered to tumor-bearing mice by oral gavage (po). Tumors werecollected at different time points followed by RNA isolation, cDNAsynthesis, and TaqMan® reactions with the kits: mRNA Catcher™(Invitrogen) and TaqMan® (Applied Biosystems), respectively. TaqMan®reactions were done in quadruplicate using duplexed probes for Gli1(target) and GAPDH (control). Additionally, whole blood was collectedand plasma prepared for bioanalytical analysis of compounds.Bioanalytical analysis of crude tumor lysates was also done.

Panc-1 Human Pancreatic Cancer Cell Line

Panc-1 human pancreatic ductal carcinoma cells were found to express theSHh ligand. The mouse Hh responsive genes (Gli1 and Ptch1) were found tobe upregulated in the mouse stromal compartment in Panc-1 tumors grownin female nude mice hosts and administration of Hh pathway inhibitorsreduced the expression level mouse Gli1 and Ptch1. In contrast, nosignificant inhibition of the human Hh responsive genes following Hhinhibitor administration in mice harboring Panc-1 tumors was observed.Therefore, Panc-1 xenografts tumors represent clinically-relevant modelof pancreatic tumors that secrete SHh and regulate the activity of theHh pathway in the stromal compartment that supports tumor growth. Themajority of human pancreatic adenocarcinomas and its precursor lesionabnormally express SHh. In addition, the forced expression of SHh in aprostate xenograft tumor model has been shown to enhance tumor growth.For implantation in vivo, 3×106 cells in 100 μL cold Hanks balanced saltsolution were injected into the right hind flank of female nude mice.

HT-29 Human Colon Cancer Cell Line

HT29 cells represent differentiated human colon aednocarcinoma. Thiscell line was reported in the literature to respond to exogenous SHhstimulation. Analysis revealed overexpression of SHh and IHh ligands.The mouse Hh responsive genes (Gli1 and Ptch1) are upregulated in themouse stromal compartment in Panc-1 tumors grown in female nude micehosts and administration of Hh pathway inhibitors reduced the expressionlevel mouse Gli and Ptch1. In contrast, no significant inhibition wasobserved of the human Hh responsive genes following Hh inhibitoradministration in mice harboring HT-29 tumors. Therefore, HT-29xenograft tumors represent clinically-relevant model of colon tumorsthat secrete SHh and regulate the activity of the Hh pathway in thestromal compartment that supports tumor growth. It has been reported inthe literature that dysregulation of SHh pathway is very often found inhuman colorectal cancers. In addition, the forced expression of SHh in aprostate xenograft tumor model has been shown to enhance tumor growth.Therefore, HT-29 xenograft tumors are a relevant model to investigatethe effect of SHh pathway inhibitors in human colorectal adenocarcinoma.For implantation in vivo, 2×10⁶ cells in 100 μL cold Hanks balanced saltsolution were injected into the right hind flank of female nude mice.

U-87MG human glioblastoma cell line

U-87MG cell line was previous described in the literature to besensitive to Smo inhibitor cylopamine treatment, both in vitro and invivo studies. In addition, this cell line was reported to express anumber of sternness genes, indicating presence of tumor stem cells,which may be responsible for tumor self-renewal and regrowth afterfollowing chemotherapy. Significance of stem cells for clinical courseof glioblastomas appears to be well established, and targeting this cellpopulation with Hh inhibitors may provide therapeutic advantage. Thus,U-87MG globlastoma xenografts can provide a valuable and relevant animalmodels for testing the effect of Hh pathway inhibitors on stemcell-driven regrowth and chemoresistance of CNS tumors. For implantationin vivo, 2×10⁶ cells in 100 μl cold Hanks balanced salt solution wereinjected into the right hind flank of female nude mice.

Biological Example 10 Pharmacodynamic Study Protocol

Subcutaneous xenograft tumors were generated in nude mice as describedabove. Compounds were administered to tumor-bearing mice by oral gavage(po) in formulations that were specific to each chemical scaffold, whichvaried from solutions to homogenous suspensions. Tumors were collectedat different time points followed by RNA isolation, cDNA synthesis, andTaqMan® reactions with the kits: mRNA Catcher™ (Invitrogen) and TaqMan®(Applied Biosystems), respectively. TaqMan® reactions were done inquadruplicate using species-specific probes for mouse and human Gli1,Ptch1 and GAPDH (control). Whole blood and crude tumor lysates werecollected and prepared for bioanalytical analysis to determine theconcentrations of the test compounds.

Biological Example 11-12 Efficacy Study Protocols Single Agent Treatment

The standard experimental design for these studies involved oraladministration of Smo inhibitors at dose range expected to modulate theHh signaling pathway based on PD studies. The dosing regimen isinitiated when the established solid tumors reached ˜100 mg. Explorationof alternative dose regimens was also performed by administration of thecompounds in a cyclical fashion (q2d or q3d). Throughout the dosingperiod of 14 days, tumor size was measured twice weekly and body weightwas measured daily. Tolerability was monitored in these studies by dailymeasurement of body weight. Blood plasma samples were collected forclinical chemistry and hematology analysis and to determine plasmaprofile of compound concentration.

Combined and/or Sequential Treatment with Standard Chemotherapeutics

Cancer stem cells are defined as discrete cell populations that expressspecific cell-surface markers and display highly enhanced survival,self-renewal, and tumorigenicity properties. These cancer stem cells, insome experimental contexts described in the literature, have shown toconfer resistance to currently used chemotherapy. In the literature, thehedgehog pathway has been shown to be essential for stem cell renewal intumors of the breast, central nervous system, and in multiple myeloma.Further, upregulation of Hh signaling has been described in theliterature following chemotherapy in an esophageal cancer model.Pancreatic cancer and gliomas are among the most chemoresistant humanmalignancies and sternness gene expression profile (“stemnesssignature”) was described in clinical samples as well as in xenograftmodels of both tumor types in the literature. These tumors models areused to address if inhibitors of Hh pathway can potentiate efficacy ofstandard chemotherapeutic agents when administered in combined treatmentor defer tumor regrowth when used sequentially after the administrationof a chemotherapy. Antimetabolite treatments, such as gemcitabine, areused in combination in Panc-1 pancreatic cancer and temozolomide, analkylating agent, are used in U-87MG glioblastoma tumor xenograftmodels.

In concurrent combination treatment, Hh pathway inhibitors areadministered in combination with the standard chemotherapy agents(gemcitabine or temozolomide). Single agent treatments are conducted toevaluate potential additive or synergistic effects when the compoundsare administered in combination. The dosing regimen is initiated whenthe established solid tumors reached ˜100 mg. Throughout the dosingperiod of 14 days, tumor size was measured twice weekly and body weightwas measured daily. Tolerability was monitored in these studies by dailymeasurement of body weight. Blood plasma samples were collected forclinical chemistry and hematology analysis and to determine plasmaprofile of compound concentration.

In sequential regimens, single agent standard chemotherapeutics(gemcitabine or temozolomide) are administered for a period of 14 daysto inhibit tumor growth and/or induce tumor regression. Subsequent tothe standard chemotherapeutics treatment, Hh inhibitors are dosed todetermine their effect on tumor regrowth. Treatment with Hh inhibitorscan be initiated immediately after completion standard chemotherapy orafter certain “off-treatment” period, depending on the study design. Thedosing regimen is initiated when the established solid tumors reached˜100 mg. Throughout the dosing period of 14 days, tumor size wasmeasured twice weekly and body weight was measured daily. Tolerabilitywas monitored in these studies by daily measurement of body weight.Blood plasma samples were collected for clinical chemistry andhematology analysis and to determine plasma profile of compoundconcentration.

Immunohistochemistry

At the termination of efficacy studies, tumors were excised and examinedhistologically for induction of apoptosis (TUNEL), microvessel density(CD31 staining), proliferating cells (Ki67 staining) and necrosis(hematoxylin/eosin staining). Additionally, tumor sections were stainedfor expression of SHh pathway (Gli1, SHh, Smo) and biomarkers of cancerstem cells (e.g. Nestin, CD131, ALDH). Tolerability was monitored inthese studies by daily measurement of body weight. Blood plasma sampleswere collected for clinical chemistry and hematology analysis and todetermine plasma profile of compound concentration.
